PREPARATION PROCESS OF PAPER FOR INCREASING FILLER CONTENTS AND ENHANCING SCOTT INTERNAL BOND STRENGTH

摘要

Disclosed is a preparation process of paper for increasing the contents of the inorganic fillers in the paper and enhancing Scott internal bond strength. Additional to a conventional preparation process of paper, as a cellulase type enzyme, an enzyme produced by Trichoderma longibrachiatum which has a carboxymethylcellulase activity of 3,600 U/ml or more is added to a pulp in an amount of 0.01 ~ 0.2 % by weight based on the weight of the wood pulp. The contents of fillers in the paper is increased and Scott internal bond strength is enhanced.
